Question

我用测试atm来覆盖系统的这一部分，我的事件链接的方式是首先停止传播必须取消第二个事件才能解雇。

$.fn.extend({
        OnTheMoveBCTrigger: function (name, options) {
            if (!(this[0] instanceof OnTheMove_BusinessComponent)) {
                throw ('is not an instance of OnTheMove_BusinessComponent');
            } else {
                var event = $.Event(name);
                var promise = $(this).OnTheMoveTrigger(event, options);
                if (!event.isPropagationStopped()) {
                    $(onTheMove.PageDataRoles).OnTheMoveTrigger(name, options);
                }
            }
        }
    });

我想了解如何使用jasmine-jquery spyOnEvent

检查第二个事件是否被触发

    it("OnTheMoveBCTrigger chain fires event on onTheMove.PageDataRoles", function () {
        var spy = spyOnEvent(onTheMove.PageDataRoles, 'event2');
        $(window.bc).OnTheMoveBCTrigger("event2");
        expect('event2').toHaveBeenTriggeredOn(onTheMove.PageDataRoles);
        expect(spy).toHaveBeenTriggered();
    });

但现在我需要测试传播正在停止而第二个事件没有被触发的情况 如何检查事件是否未被触发？

Jasmine not上有expect属性，允许反转支票下面的代码对我有用。

    it("OnTheMoveBCTrigger does NOT chain fire event on onTheMove.PageDataRoles, if propogation is stopped on BC event.", function () {
        var spy = spyOnEvent(onTheMove.PageDataRoles, 'event3');
        $(window.bc).on("event3", function (e) {
            e.stopPropagation();
        });
        $(window.bc).OnTheMoveBCTrigger("event3");
        expect('event3').not.toHaveBeenTriggeredOn(onTheMove.PageDataRoles);
        expect(spy).not.toHaveBeenTriggered();
    });

测试是否在Jasmine间谍元素上没有触发事件
